Primary Outcome Measures

Name	Time	Method
Gastric emptying time	1 hour	The time for digesting a meal

Secondary Outcome Measures

Name	Time	Method
Incidence of full stomach	At 4, 5, 6, 7, and 8 hours after eating a meal.	The incidence of full stomach is assessed by using ultrasonography.
Gastric volume	At 4, 5, 6, 7, and 8 hours after eating a meal.	The volume of stomach is assessed using the following formula; volume of stomach (mL) = 27.0 + 14.6 x cross-sectional area (right lateral position) - 1.28 x age.
Type of gastric contents	At 4, 5, 6, 7, and 8 hours after eating a meal.	The type of gastric contents is assessed using ultrasonography.
Cross sectional area of the stomach	At 4, 5, 6, 7, and 8 hours after eating a meal.	The cross sectional area of the stomach is assessed by using ultrasonography in the supine and right lateral positions.
